Mitchell writes that "a few months back" she and her husband Michael received news that they were pregnant with twins. Like many would do, the couple, who have two children aged three and five, began preparing for the expansion of their family. But a few weeks later, the 37-year-old suffered a miscarriage.

"Honestly, my first instinct was to say I was fine, and to be honest; I was trying to be. I thought I had to be, for my family, for myself," Mitchell continues.

The actress shared how even though she tried to rationalize her miscarriage, it was still a shock, given that she'd previously had two healthy pregnancies.

"It wasn’t until I started sharing our loss that I found out many people I knew shared the same scars," the "7th Heaven" star wrote. "I was now part of a group, the unspoken and hidden group who mourn their losses in the shadows. This was the hardest part, suffering in silence."

Mitchell then thanked her "rides or dies" who supported her through her miscarriage and allowed her to heal. She ended the blog post by encouraging others to share their own stories.

"Today, I share my scars because the one thing I want to say, is no one should suffer in silence. To speak up and share your wounds, to allow them the opportunity to heal. Let’s remove the stigma, miscarriages happen, they are nothing to be ashamed of."
